Technical Field

In the field of electronic device manufacturing, many processes, such as photolithography and etching, require a high degree of cleanliness. However, in actual production, even in cleaned and cleaned plants, clean rooms and the like, tiny dust particles have great quality influence on electronic devices. Dust cleaning on the associated operating platform is therefore particularly necessary. However, on a common operation platform, static electricity is inevitably generated, and the static electricity is often formed on the surface of the electronic component due to contact, friction and the like, and the formed static electricity may generate attraction force to fine particles such as dust and the like, so that the fine particles are adsorbed on the surface of the electronic component, thereby generating pollution. In addition, when the static electricity is accumulated to a certain amount, the static electricity discharge will be generated, which will damage the electronic device. Therefore, in industries requiring high precision, it is necessary to eliminate static electricity from the work surface as well as to keep the work surface clean.
